SC200AR0 Bearing Product Overview & Core Advantages
The Reali-Slim Stainless Steel Bearings represent a specialized category of thin section bearings engineered for applications requiring compact design and high precision. This single row angular contact ball bearing with a 20-inch bore is constructed entirely from stainless steel, offering excellent corrosion resistance. Its defining feature is the 30° contact angle, which is optimized to support significant combined loads—handling both radial and axial forces simultaneously. With an ABEC-1 precision class and a compact cross-section, it delivers reliable performance in space-constrained, high-accuracy systems.

| Seal Type | Open | Allows for custom lubrication schemes and minimizes rotational torque. |
| Contact Angle | 30° | Optimized for supporting high axial loads in combination with radial loads. |
| Tolerance Class | ABEC-1 | Specifies standard precision for runout and dimensional accuracy. |
SC200AR0 Bearing Structural Features & Performance Benefits
The bearing's performance is a direct result of its specialized construction. The stainless steel rings and balls provide superior corrosion resistance, making it suitable for harsh environments. The brass cage ensures stable ball guidance and is suitable for a wide range of operating conditions. The 30° contact angle is critical for its ability to handle combined radial and axial loads effectively. Despite its thin cross-section (0.375" width), it offers a high static load moment rating of 34,720 lbf, indicating exceptional rigidity and resistance to moment loads. The tight radial internal clearance (0.0000 – 0.0005") contributes to precise shaft positioning and smooth operation.
